I suspect Intel has a broader product range than AMD to justify the headcount, but I’m not sure where the extra resources should go.
Their networking chipsets were gold-standard in the 100M and Gigabit era, but their 2.5G stuff is spotty to the point Realtek is considered legit.
They’ve pulled back from flash, SSDs and Optane.
There must be some other rich product lines that they do and AMD doesn’t
Or that there’s a huge amount of legit demand for mature node chips and it makes sense to own the supply for it.
The 5000 microcontrollers you inyeract with each day, by and large, do not need 5nm processes.
We saw a few years ago how relatively cheap, commodity-grade, low-complexity chips suddenly become vital when you can’t get them and they have unfinished cars piling up at the assembly plant.
